To al?, whom it puny cm1/cern:

Be it known that I, ALPHONSE DE FONTAINE, director, a subject of theKing of Prussia and Emperor of Germany, residing at Dr. Otto- 5 strasse119, Dahlhausen-on-the-Ruhr, in the Kingdom of Prussia and Empire ofGermany, have invented certain new and useful Improvements in Apparatusfor Rolling Disk fheels or Similar Articles, of which the following isIO a full, clear, and exact description.

The apparatus forming the subject of the present invention and which isfor rolling disk wheels and similar articles is intended exclusively foruse in rolling-mills in which the I5 work is to be treated by means ofconicallyshaped rollers. A treatment of this kind has heretofore onlybeen effected as a so-called finishing operation, because the blocks tobe treated have always had to be forged as a preliminary operation, asthe conical rollers served only to give the final shape to the work.

Now the apparatus forming the subject of the present invention isdesigned to effect the complete rolling out of the disk, so that thepreparatory forging ofthe blocks becomes superiiuous. Rolling-mills ofthis kind have always been constructed heretofore in such a manner thatthe conical rollers were mounted on shafts arranged at an angle to eachother,

so that the work which was already forged to the shape of a disk wasfixed between the said rolls either vertically or horizontally,accordingto the position of the rolls. Apart from the fact that theconstruction of such rolling-mills was Very complicated in consequenceof the angular position of the axes of the rolls it was necessary inorder to enable accurate work to be produced to arrange one roller(generally the so-called f pressureroller,7 operated by hydraulicpressure) in an adjustable manner in its axial direction, so thatthesaid roller should always be at the same height as the so-calleddriving-roller during the rolling operation. Now according totheimprovement hereinafter described the adjustability of the so calledpressureroller is rendered superfluous and also the angular arrangementof the axes of the rolls is entirely avoided. rThe consequence of thisarrangement is that any rolling-mill frame, and especially the frame ofthe twyer rollingmill, which is to be found as a necessary constituentof the entire rolling-mill, can be utilized. This isamost importantpoint, because such rolling-mill frames are to be found in every largeworks. The improvement is substantially characterized by the fact thatthe so-called driving-1olle1"is mounted horizontally on thedriving-spindle, (which is arranged vertically in the usualrolling-mills,) while the ,so-called pressing-roll is mounted obliquelyupon the table which moves at right angles to the driving-spindle. Withthis arrangement of rolls the Work is fixed, not horizontally orvertically, but obliquely-M that is to say, so as to be capable ofvertical adjustment parallel to the sides of the rolls which operateupon it--the said work being carried by a supporting-spindle, which isarranged at right angles to opposite generatrixes of the surfaces of therolls and which is capable of being adjusted in its distance from therolls. This last circumstance has two advantages: First, disks ofdifferent sizes can be rolled by means of one and the same pair ofrollers, according to the vertical position of the supporting-spindle,and, second, by altering the position of the supporting-spindle as toheight during the operation the adjustability of the pressing-roller inits axial direction, which would otherwise be necessary,

is obviated. In order to be able to roll the rim of the disk at the sametime as the latter is being rolled out, a further suitably-shaped rolleris provided on the frame of the rollingmill, and it is supported in anadjustable manner.

trate my improvements, Figure 1 isa side elevation` partly in section,showing the rollingmill. Fig. 2 is a plan, and Fig. 3 is a cross-sectionthereof.

' The frame of the rolling-mill is similar to that which is suitablyemployed for rolling tires. It consists, substantially, of the frame r,which serves to support the vertical driving-shaft p and also thehydraulically-operated carriage s with the piston 7c and the cylinder e.Upon the vertically-arranged driving-shaft p there is mounted in ahorizontal manner the conically-shaped roller a, which is mounted on itsshaft in the simplest manner, preferably by keying. The so calledpressing-roll b is mounted, on the contrary, obliquely on the carriages, for which purpose there is employed a conically-shaped pin or journalc, upon the uppery stepped end c of which the roll b is mounted in arotary manner, while the pin is fixed by means of its square parts 02 03to the carriage s or to a bracket t, bolted thereto.

The carriage s is moved in the frame 1' by means of the piston 7c byhydraulic power forward in the usual way, while the return movement ofthe carriage is effected by means of hydraulic power acting upon apiston o, that is guided in a cylinder y, preferably arranged below thecylinder e, by means of the pistonrod u, which is connected to thebracket t, or steam-power may be used for this purpose. The block toform the disk gis fixed between the opposite or facing sides of the tworollers a and at an inclination to the horizontal sides of the rollersand so as to be adjustable as to height parallel to the sides of thesaid rollers. This is effected by mounting the block on avsupporting-spindle L, which is arranged at right angles to the oppositegeneratrixes of the surfaces of the rolls and which is guided adjustablyas to height parallel in its distance from the rolls by means of itssquare part /L in the bearing-frame t'. The bearing-frame t' ispreferably made to embrace roll a, so that the latter is containedalmost completely in the bearing-frame, and it can be provided with anysuitable adjusting device for adjusting the part h' of thesupporting-spindle L during the working. This is effected, as abovementioned, in order to avoid the formation of steps in rolling out thedisks, which could otherwise only be effected by mounting thepressingrolls in an adjustable manner. For the purpose' of forming therim g/ there must be provided a further and specially-formed roll f, thebearing m of which is mounted adjustabl y in guides n on the frame, sothat the roll f is adjustable parallel in its distance from the work. Itwill be advisable for the purpose of enabling the bearing to be shiftedduring the working to connect it with the spindle B (which is alsoarranged in the block A in such rolling-mill frames) by means ofthe'carriage D and the press-rod E, so that by rotating the spindle Binthe ordinary manner the roll f can be adjusted to the correct positionfor the purpose of forming the rim of the disk.

It will be noted that in the specific construction and arrangement asembodied in my invention and improvements the apparatus comprises, inassociation with a verticallyarranged driving spindle, ahorizontallymovable carriage and conically-shaped rolls mounted,respectively, on the driving-spindle and obliquely on the movablecarriage, that the supporting-spindle which is adapted to carry the workis adjustable parallel to itself in the plane of the geometrical axes ofthe rolls and in the direction of the line which constitutes thebisector of the angle formed by the aXes of the rolls, and that the rollfor lforming the rim is adjustable parallel in its distance from thework.

I/Vhat I claim, and desire to secure by Letters Patent, is-

l. In an apparatus for rolling disk wheels and similar articlesembodying a verticallyarranged driving-spindle, a horizontally-movablecarriage and conically-shaped rolls mounted respectively on thedriving-spindle and obliquely on the movable carriage, asupportingspindle adapted to carry the work and adjust'- able parallelto itself in the plane of the geometrical axes of the rolls and in the`direction of thc line which constitutes the bisector of the angleformed by the axes of the rolls.

In witness whereof I subscribe my signature in presence of twowitnesses.
